Sasuke vs. Bee was mehh, a cool fight but Sasuke being killed and revived twice destroyed the whole thing.

Jiraiya vs. Pain was epic in my opinion but Jiraiya's Sage Mode was kinda disappointing, he barely beat 3 paths and after that PUFFF he gets beaten.

Itachi vs. Sasuke, again epic but Sasuke trembling in fear by seeing his brother in the merge of killing him showed Sasuke's lame part.

Naruto vs. Pain, nice fight, epic moment of Kyuubi's release but Chibaku Tensei was too lame, I expected some huge ass technique but Naruto escaped it easy and it wasn't much of a thing, he barely got kept in that technique aand that lame BEEP BEEP animation.

Sasuke vs. Danzo, well this one was a good fight, not really epic since Sasuke being a young shit beaten Danzo which was so much older than him and only had some Fuuton techniques and some summoning, even with the 10 Sharingans Izanagi got beaten, that made Sasuke too overrated, that was the moment which started the Sasuke is better than Itachi, but the end was epic, Sasuke killing Karin, that moment I loved, when Sasuke lost all the good side in his heart which was shown in the fight against Bee.

This fight is the most interesting among all. Sasuke utilized his skills most in this battle. The way he analysed the flow of battle in order to countered izanagi and took down Danzo, was just pure genius.
